Lenovo ThinkSystem RAID 940 Series Internal RAID
Adapters
Product Guide
The ThinkSystem RAID 940 family of PCIe 4.0 12 Gbps SAS RAID controllers are high-performance RAID-
on-chip (ROC) server adapters for connectivity to drives internal to the server. These adapters support
RAID levels 0, 1, 10, 5, 50, 6 and 60, and include an extensive list of RAS and management features.
The ThinkSystem RAID 940-16i is shown in the following figure.

Did you know?
The RAID 940 Series adapters all have a PCIe 4.0 host interface which doubles the bandwidth between the
server and the adapter, compared to the previous generation RAID 930 adapters. This improves overall
performance of the storage subsystem by supporting up to 3 million IOPS (JBOD mode) and up to 3 million
IOPS in RAID (random reads).
RAID on Chip-based controllers such as the RAID 940 adapters have a dedicated processor that offloads
all RAID functions from the server's CPU. With hardware acceleration for RAID 5 and 6 operations plus up
to 8 GB dedicated memory for caching, the 940-8i, 16i and 32i offer the ultimate performance for
ThinkSystem servers.

Part number information
The following table provides the ordering part numbers for the adapters.
The table includes feature codes for the RAID 940 adapters to be ordered with the Tri-Mode feature
enabled. Tri-Mode enables the support of SAS, SATA and NVMe drives to be connected to the adapter, as
described in the Features section.
